Industrial Applications

1. High-resolution inspection of small printed features

The 16 mm focal length, 5 MP class resolution, and visible-light optimization suit inspection stations that must resolve fine print, codes, or micro-features on flat parts.

Problem Solved

Maintains sharp imaging of small structures without excessive geometric distortion.

2. Medium-distance machine vision on production lines

The 0.2 m to infinity focus range and 0.5 m optimum working distance make it practical for conveyor-mounted cameras inspecting parts at moderate standoff distance.

Problem Solved

Provides stable framing and focus for fixed-station automation cells.

3. Quality control in controlled indoor industrial lighting

The lens is optimized for visible wavelengths, has 55% full-aperture illumination, and a metal housing with locking focus/iris, making it appropriate for repeatable QC imaging where settings must not drift.

Problem Solved

Prevents focus and aperture movement under vibration while preserving consistent image contrast.
